`LOGOMOT|VE SAND-DELIV'ERING PIPE.

SPECIFICATION forming part of Letters Patent No. 709,414, datedSeptember 16, 1902.

`" VApplication filed October 16. 1901. Serial No. 78,886. (No model.)

Be it known that I, ISAAC T. LEWIS, avitizeuof the UnitedStates,residingin Philadelphia, Pennsylvania, have invented certainImprovements in LocomotiveSaud-Delivery Pipes, of which `the followingis a specica tion.

The object of my invention `is to provide the lower or delivery end ofthe track-sanding pipe of alocomotive with means whereby upon t-he trackwhen the locomotive is rounding a curve or in other cases where thedelivery-pipe vas usually constructed would direct the sand off to oneside ot'` the rail in-` stead of upon the top or tread of the same. Thisobject I attain by providing lthe lower end of the sand-delivery 'pipewith a laterally- .swinging nozzle which may be permitted to `assume itspropel' position by gravityor may 1 be positively controlled from` Athecab on the engine.

V In the accompanying drawings, Figure 1 is `a side view illustrating myinvention, stiflicient of the locomotive being shown in dotted lines toillustrate the application of the in` vention thereto. Fig. 2 is a planView. Figs. Sand 4 are sectional views illustratingr the f. lower endofthe sand-de1ivery pipe with my improved swinging nozzleappliedthereto. Fig. 5 is an` elevation of the same, and Figs.

` `6 and 7 are diagrams illustrating the conditions under which myinvention is designed `to be used.

In'Fig. 1 theusual sand-delivery pipes of a locomotive are representedat l, these pipes being disposed, asusual, so as to deliver sandrespectivelyin front of the forward driver and behind the rear driver.lThe lower end of the pipe is, however, provided with a fixed nozzle 2,which terminates iu a vertical depending portion having oppositeprojecting n `studs or trunnions 3, which are in line with j thelongitudinal wheel-base ofthe engine,

so that the cen ter of` each of these nozzles is directly over thecenter of its corresponding rail'whennthe engine is running uponsand-delivery pipe will be so far out ol.' proper vertical alinementwith the center of the railtread that it will deliver its sand to oneside or the other of said tread, and hence will fail to perform itsintended duty. This 'will be understoodon reference to thediagram Fig.

6, in which the, dotted curves represent lines of track and the circlesrepresent fixed sandde'livery pipes occupying lheir ordinary relation tothe driving-wheels of the engine. This tendency to deliver the sand tovone side or other of the tread of the rail is enhanced by the tiltingofthe engiue,beeause of the customary rise of the outer rail of thecurve, as shown in Fig. 7. This tilting ot' the engine, and consequentlyoi' the sand-delivery pipes, causes the latter to throw the sandoutwardly or inwardly instead of in a directdownward course. 'In orderto overcome these objections, I hang upon the trunnions 3 of the fixednozzle 2 a swinging `nozzle 4, which has suitable sockets 5 for thereception of the trunnions 3, accidental displacement of the swingingnozzle 4 being prevented byv means of` cotter-pins G or in anyothersuitable manner. The natural tendency of the nozzle 4 is thereforealways to assume a vertical position, so as to deliver sand directlydownward therefrom onto the head of the rail, any lateral deiiection ofthe sand due to the tilting' of the engine and sand-delivery pipes beingtherefore effectually overcome. \Vherethe curve is of very small radius,however, it inay benecessary to swing the nozzle 4 inwardly or outwardly`beyond the vertical plane, as shown, for instance, by dotted lines inFig. 5. so as to cause it to deliver sand onto the head of the rail, andI therefore provide means whereby the occupant of the cab can effect thepositive adjustment of the swinging nozzle in either direction. Thesedevices are shown in Figs. 1 and 2 and comprise transverse rods 7, eachpivoted to projectinglugs 9 on swinging nozzles 4, carried by thesanddelivery pipes on opposite sides of the engine, each of these rods 7being connected by a link 10 to an arm 11 on a longitudinal rockshaft12, suit-ably mounted in bearings on the engine-truck, and havinganother arm 13, which is connected by a rod 14 to an arm 15 on arock-shaft 16, having another arm 17 projecting up into the cab, so asto be within convenient reach of the engineer or fireman. Hencesimultaneous swinging of all of the nozzles to right or left o l"v acentral vertical line can be readily effected in accordance with therequirements of the particular piece of track over which the engine isrunning, so as lo cause the delivery of the sand directly onto thetreads of the rails u nder all circumstances.

v I am aware that sand-pipes of locomotives have been provided withnozzles mounted so as to be swung longitudinally or in a direc-` -tionparallel with the length of the rail, so as to direct the stream of sandmore or less nnder the-driving-Wheel; but it Will be evident that suchnozzles are different from the laterally-swinging nozzles which I employand are not capable of attaining the object for WhichY my swingingnozzles haveV been designed. Without claiming broadly, thereiore, alocomotive sand-pipe having a swingp ing delivery-nozzle,

I claim and desire Ato secure by Letters Patent- l. The combination ofopposite sand-delivery pipes of a locomotive, a transverselypipe, atransverse rod connecting said nozzles, l

a longitudinal rock-shaft having an arm connected to said rod, andconnections from said rock-shaft to the cab of the locomotive,substantially as specified.

2. A locomotive sand-pipe curved to conform to the Wheel and havingsecured to its lower end a fixed nozzle with vertical delivery end, anda nozzle mounted thereon so as to swing in a direction transversely tothe rail, substantially as specied.

3. The combination of locomotive saud-y pipe with a fixed nozzlesecuredthereto and having a delivery portion with fore and aft trunnionsprojecting therefrom and a swinging delivery-nozzle having sockets forthe reception of said, trunnions, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribingu Witnesses.

ISAAC T. LEWIS.
